What are the technical barriers to heat soaked glass?

The technical barriers to heat soaked glass mainly involve the following aspects:

Temperature Uniformity Control: Ensuring uniform temperature distribution within the furnace is a key challenge during hot soak processing. Due to the common problem of large temperature differences in domestic hot dip furnaces, this may cause the glass to be heated unevenly during the hot dip treatment, affecting the crystal phase change of nickel sulfide, thereby affecting the reduction effect of the self-explosion rate. Although the temperature difference of stoves imported from abroad is small, there is still a certain temperature difference, which is also a technical problem that needs to be solved.

Process parameter optimization: The temperature, time and other parameters of the hot dip treatment have an important impact on the final effect. How to determine the optimal heat soak treatment parameters based on the material, thickness and other characteristics of the glass is a technical problem. In addition, with the introduction of new standards, how to reduce the time and energy consumption of heat soak treatment while ensuring the effect is also an issue worth studying.

Glass surface protection: During the heat dipping process, how to prevent scratches or contamination on the glass surface is another technical barrier. This involves the control of the heat immersion environment, the selection and use of tools, and the application of protective materials.

Equipment design and improvement: The design and manufacturing of hot dip furnaces is also a technical difficulty. How to design a reasonable furnace structure, heating method, insulation materials, etc. to ensure uniform temperature in the furnace, energy saving, high efficiency, and easy maintenance is an important technical issue in the production of heat soaked glass.

Material selection and research and development: In the production process of heat soaked glass, material selection and research and development are also important technical barriers. For example, finding glass formulas that can better resist thermal stress and reduce the rate of self-explosion, or developing new protective materials to reduce scratches and contamination on the glass surface are current research hotspots.

The technical barriers to heat soaked glass involve many aspects, and multiple factors such as materials, processes, and equipment need to be comprehensively considered to continuously improve the quality and performance of heat soaked glass.
